Lucía needs 13.33 feet of cotton.
Since Lucía makes braided key chains out of cotton cord, and for every 8 feet of cotton cord she has, she can make 3 braided key chains, to represent the relationship between the feet of cotton cord and the number of key chains and find the number of feet of cotton cord Lucia needs to make 5 key chains, the following calculations must be performed, through a cross multiplication:
- 8CC = 3KC
- 3 = 8
- 5 = X
- 5 x 8/3 = X
- 40/3 = X
- 13.33 = X
Therefore, Lucía needs 13.33 feet of cotton.
